A method of driving a plasma display device, having a time-divisionally driven gray scale utilizing a reset period in which wall charges of all cells of a plasma display panel (PDP) are initialized, an address period for enabling a sustain discharge by generating a weak discharge in selected cells, and a sustain period in which the sustain discharge is generated in the selected cells. Further, an erase discharge is generated in all the cells of the PDP early in the sustain period.

摘要:
A driving method of a plasma display device according to an exemplary embodiment groups a plurality of address electrodes extending in a first direction into a plurality of groups, and logically divides each of the groups into a plurality of sub-groups. During a first period, a first pulse is sequentially applied to the plurality of groups, and a second pulse is sequentially applied to the plurality of sub-groups included in at least one of the plurality of groups during a second period following the first period. The first and second periods are address periods for sensing in a second direction crossing the first direction.

A plasma display device and a power supply thereof having a fewer number of power sources in the plasma display device is disclosed. The power supply generates a voltage corresponding to a Ve power source by using a variable resistance through a voltage distribution principle without including a Ve power source. In addition, since a power supply circuit including a thermistor is used in order to correspond to a discharge firing voltage which is changed by a temperature, a sustain discharge is stably generated by adjusting a Ve voltage without including a Ve power source.
摘要:
In a sustain period, a positive voltage is applied to an address electrode during at least one part of a period for applying a last sustain discharge pulse that is gradually increased and applied to a scan electrode. In this manner, an occurrence of misfiring between the address electrode and the sustain electrode of a discharge cell that is sustain-discharged without having been addressed in the next consecutive subfield is reduced or prevented.

In a plasma display and a driving method thereof, a misfiring prevention period is provided between a reset period and an address period in response to a temperature of the plasma display being higher than predetermined temperature or a weight value of a previous subfield being higher than a predetermined weight value. In the misfiring prevention period, a first voltage higher than a voltage supplied to a sustain electrode is supplied during a first period, and a voltage at a scan electrode is gradually decreased from a second voltage to a third voltage during a second period subsequent to the first period.
